Toxic Proteins in Neurodegenerative Disease

Taylor, J. Paul, Hardy, John, Fischbeck, Kenneth H.·2002·Science

Abstract

A broad range of neurodegenerative disorders is characterized by neuronal damage that may be caused by toxic, aggregation-prone proteins. As genes are identified for these disorders and cell culture and animal models are developed, it has become clear that a major effect of mutations in these genes is the abnormal processing and accumulation of misfolded protein in neuronal inclusions and plaques. Increased understanding of the cellular mechanisms for disposal of abnormal proteins and of the effects of toxic protein accumulation on neuronal survival may allow the development of rational, effective treatment for these disorders.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Abnormal aggregation of APP-cleaved Aβ peptide and phospho-Tau highlights substantial deregulation of posttranslational events in AD.

    “For example, abnormal aggregation of APP-cleaved Aβ peptide and phospho-Tau highlights substantial deregulation of posttranslational events in AD (Taylor et al., 2002).”
  • Accumulation of toxic protein species can kill neurons, and there is growing evidence that ER stress is an important mechanism driving this neurotoxicity.

    “Accumulation of toxic protein species can kill neurons, and there is growing evidence that ER stress is an important mechanism driving this neurotoxicity [395].”
  • The buildup of neurotoxic agents causes neuronal damage and death, which can lead to neurological dysfunction including cognitive decline, motor abnormalities, mental disorders, and loss of inhibition.

    “The buildup of neurotoxic agents is believed to cause neuronal damage and death, which can ultimately lead to various forms of neurological dysfunction that include cognitive decline, motor abnormalities, mental disorders, and loss of inhibition (Chung et al., 2018; Taylor et al., 2002; Vickers et al., 2009).”

  • Many neurodegenerative diseases have known causes involving mutations in ubiquitously expressed proteins, yet they follow stereotyped degeneration patterns that selectively affect certain cell subsets, producing disease-specific spatial and temporal patterns.

    “Many of these diseases have known causes that involve mutations in ubiquitously expressed proteins134, but they follow stereotyped patterns of degeneration that selectively affect certain cell subsets more severely, resulting in disease-specific spatial and temporal patterns of degeneration135–137 (BOX 1).”
  • Nearly every neurodegenerative disorder is marked by accumulation of misfolded proteins within or adjacent to affected neurons and glia.

    “This notion is underscored by the fact that nearly every neurodegenerative disorder is marked by the accumulation of misfolded proteins within or adjacent to affected neurons and glia, in spite of heterogeneous clinical and pathological characteristics among these diseases [68,69].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
